Michael Anthony Knyszek c803ffc67d runtime: scavenge large spans before heap growth 
This change scavenges the largest spans before growing the heap for
physical pages to "make up" for the newly-mapped space which,
presumably, will be touched.

In theory, this approach to scavenging helps reduce the RSS of an
application by marking fragments in memory as reclaimable to the OS
more eagerly than before. In practice this may not necessarily be
true, depending on how sysUnused is implemented for each platform.

Fixes #14045.
